I am looking for a way to solve the following problem:
User should only be able to visit mywebsite.com/page2 after they visited mywebsite.com/page1.
If a user was not on page1, he or she should not be able to visit page2.
Is this possible?
Further specification: On page1 should be a survey (plugin: "Contact Form 7") and people are redirected to page2 after submitting their answers.
